WINDMILL.

SPECIFICATION forming part of Letters Patent No. 762,159, dated June '7,1904,

i Application filed March 26, 1904.

To all whom it may concern:

Be it known that we, JOHN E. FILLMAN and WILLIAM DAvis, citizens of theUnited States, residing at Meno, in the county of Woods, OklahomaTerritory, have invented new and useful Improvements in Windmills, ofwhich the following is a specification.

This invention relates to windmills, and has special reference to thetransmission-gear, or, in other words, the gearing interposed betweenthe wind-wheel shaft and the plunger rod or stem, whereby the saidplunger-rod is actuated by a direct stroke, thereby greatly simplifyingthe mechanism and adding to the life and durability of the same.Provision is also made whereby the stroke of the pump rod or stem may beregulated to suit the velocity of the wind and other conditions.

With the above general objects in view the invention consists in thenovel construction, combination, and arrangement of parts, as hereinfully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a front elevation of awindmill and to wer,illus trating the present invention. Fig. 2 is anenlarged side elevation of the upper portion of the mill, illustratingthe rotary head and the parts connected therewith'and mounted thereon.Fig. 3 is a sectional plan view of the head. Fig. 4-. is a verticalsection through the mechanism shown in Fig. 2, showing the manner ofgearing the wind-wheel shaft to the plungerrod. Fig. 5 is a detailperspective view of the rotary head and guide or gear-case. Fig. 6 is aview in elevation of the oscillatory bearing or swivel-head.

Like reference-numerals designate" corresponding parts in all figures ofthe drawings.

Referring to the drawings, -1 designates a windmill tower or standcomposed of any usual or suitable framework, 2 the plunger-rod, whichextends vertically through the top of the tower, 3 a pump, 4: the pumprod or stem, 5 the wind-wheel, and 6 the wind-wheel shaft, the saidparts being of any usual or preferred construction and arrangement.

In carrying out the present invention the rotary head (shown at 7) isprovided with a downwardly-extending shank or spindle por- Serial No.200,154. (No model.)

tion 8, which is received in a head tube or socket 9, mounted on theupper end of the tower or stand. The head is provided with a shoulder orbearing 10, which rests on the upper end of the head-tube 9, while astop-collar 11 is fastened on the lower end of the shank 8 and adjustedby means of a set-screw 12 for the purpose of preventing upward movementof the head under rapid rotation, at the same time permitting the headof the mill to be removed whenever necessary.

The rotary head 7 is provided with a later-' ally-projecting bracket 13,provided with a horizontally-disposed and disk-shaped table or rest 14,upon which is placed an oscillatory hearing or swivel-head 15, having adownwardly-extending stem 16, which fits and is journaled in the opening17, located centrally of the table or recess 14', as shown in Fig. 5,

the bearing 15 being provided, by preference, with an enlargeddisk-shaped base 18 to provide a proper bearing for the swivel-head onthe bracket 13 and table 14. The bearing or swivel-head 15 is providedat its upper end with ahorizontally-disposed sleeve 19,through which thewind-wheel shaft 6 passes and in which it is journaled, as shown inFigs. 2 and 3. The shaft 6 has the wheel 5 mounted fast on its outerend, while it is provided at its inner end with a pinion 20, fastthereon.

Connected with the bracket 13 is an upwardly-extending gear-case andguide 21, which may be left open at front and back and which is providedwith guide ways or grooves 22, formed by oppositely -located pairs offlanges 23, as clearly shown in Figs. 3 and 5. Mounted to reciprocate ina rectilinear path up and down within the combined guide and gear-case21 is an oblong internal gear 24,or,in other words, a gear consisting ofa rim having 'parallel sides 25 and rounded end portions 26,

while the rim as a whole is provided alongits inner face with teeth orcogs 27. The gear mounted fast on the upper end of the plungerrod 2,while said rod passes downward through the tubular portion of the rotaryhead 7 in the manner illustrated in Fig. 4:.

During the rotation of the wind-wheel the pinion 2O meshes first withone side of the internal gear and then with the other, being held inengagement with the teeth by means of the central guide 29, whichoperates on the guide-roller 30. It will be observed that theplunger-rod 2 and internal gear 24 work in a vertical and perfectlyrectilinear path, thus imparting a direct stroke or action to theplunger-rod, while the wind-wheel shaft is mounted in a swivel-head oroscillatory bearing which automatically shifts itself so as to permitthe pinion to work in constant engagement with the teeth of the internalgear 24. The windmill may be equipped with the usual tail-vane 31.

At a suitable point in the height of the tower a stroke-regulating lever32 is provided, the same being pivotally connected at one end to thetower and having the plunger-rod 2 con nected to its opposite end. Saidlever is provided with a longitudinal series of holes 33, to any one ofwhich may be connected the upper end of a pitman or connecting rod 34,the lower end of which is jointed to the pump-rod t either with orwithout the interposition of a second guide-lever 35 connected with thetower. By the means just described any desired stroke may be given tothe pump-rod 4, so as to adapt the mechanism as a whole to the velocityof the wind.

Parts of the mill not hereinabove particularly described may beconstructed or arranged in any usual or preferred manner, and changes inthe form, proportion, and minor details of construction may be resortedto without departing from the principle or sacrificing any of theadvantages of the invention.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is

1. Transmission-gear for windmills comprising a sectional head onesection of which is rotatable on the tower and the other section mountedto oscillate on the first-named section, a wind-wheel shaft journaled onthe oscillatory section, and gearing interposed between said shaft andthe plunger-rod.

2. A windmill comprising a tower, a plunger-rod, a wind-wheel shafthaving a pinion, a rotary head on the tower, a bearing for thewind-wheel shaft mounted to oscillate on the rotary head, and arectilinearly-movable gear on the plunger-rod actuated by said pinion.

3. A windmill comprising a tower, a head journaled on a vertical axisthereon and provided with an offstanding bracket, a swivelhead journaledon a vertical axis on said bracket and adapted to oscillate, awind-wheel shaft journaled in said swivel-head, a vertical plunger-rod,an oblong internal gear mounted fast on said rod, a pinion on thewind-wheel shaft meshing with said internal gear, and means formaintaining the engagement betweensaid pinion and internal gear andcausing the wind-wheel shaft to oscillate.

4. A windmill comprising a tower, a rotary head journaled on a verticalaxis thereon and provided with an oifstanding bracket, a swivelheadjournaled on a vertical axis in said bracket, a wind-wheel shaftjournaled in said swivel-head, a combined guide and gear-case connectedwith the rotary head, a verticallymovable plunger-rod, an internal gearmounted fast on said plunger-rod and working up and down in the combinedguide and gearcase, a pinion fast on the wind-wheel shaft and meshingwith the internal gear, and means for maintaining the engagement betweenthe pinion and the internal gear and causing the wind-wheel shaft tooscillate.

5. A windmill comprising a tower, a rotary head journaled on a verticalaxis thereon, a

swivel-head journaled on a vertical axis on the rotary head, awind-wheel shaft journaled in said swivel-head, a vertical plunger-rod,an internal gear mounted'fast on said rod, a combined guide andgear-case in which the internal gear moves, a pinion'on the windwheelshaft meshing with said internal gear, a central guide connected withthe internal gear, a roller on the wind-wheel shaft cooperating withsaid guide to maintain the engagement between the pinion and internalgear, a pump-rod, and a stroke-regulating 1ever interposed between thepump-rod and plunger-rod whereby the stroke of the pumprod may beregulated, substantially as described.

In testimony whereof we affix our signatures in presence of twowitnesses.
